How to create stacked rotation with bones? (similar to array mod with object offset)
Using &quot;child of&quot; constraint:

Add the constraint to each of the bones, using &quot;set inverse&quot;, relatively to its parent:

Tune the influence to be progressively decreased: 100% for the first then 75, 50 and 25 (as 4 bones in my example).
Notes:
-will work under some limits, because if too much rotation the last bones will turn over the constraint limits.
-scales are progressive too (like array modifier)
